Description

Technical Field

[0001] The present invention relates to the technical field of demolition robots, in particular to a construction demolition device. Background Art

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0033] like Figure 3-Figure 8As shown, a construction demolition device described in the present invention includes a chassis bracket 1, a fuselage 2 installed on the chassis bracket 1, a mechanical arm 3 connected to the fuselage 2, an adjusting structure 4 arranged inside the chassis bracket 1, a walking structure 5 connected to the adjusting structure 4, a rotating structure 6 coordinated with the chassis bracket 1, a climbing structure 7 connected to the rotating structure 6, and a bulldozer structure 8 installed on the chassis bracket 1; the adjusting structure 4 includes four guide rails 401 and a slide 402 slidably connected to the guide rails 401, two guide rails 401 are fixedly connected to the two side walls inside the chassis bracket 1, two slides 402 are provided between the two guide rails 401 on the same side, and the upper surfaces of the four slides 402 are fixedly connected to the rotating rod 404. A motor 405 is fixedly connected to the inner wall of the chassis bracket 1, and a driving plate 406 is fixedly connected to the output shaft of the motor 405. The two ends of the driving plate 406 are rotatably connected to the first connecting rod 407 and the second connecting rod 408, respectively. The ends of the first connecting rod 407 and the second connecting rod 408 are rotatably connected between two adjacent rotating rods 404. The sides of the four slides 402 are fixedly connected to the connecting rod 403, which is slidably connected to the inner wall of the chassis bracket 1. A walking structure 5 is provided between the two connecting rods 403 on the same side. Two driving grooves 409 are provided on the inner wall of the chassis bracket 1. A bottom cover 410 is fixedly connected to the bottom surface of the chassis bracket 1. The two pairs of guide rails 401 are symmetrically arranged, and the driving plate 406 has a "U"-shaped structure.When the device is traveling on some complex terrain with bumps, potholes or slopes, the center of gravity of the device can be distributed more reasonably by adjusting the distance between the two first crawlers 507 at the bottom of the device, thereby reducing the risk of rollover. Since the ground may have various angles of inclination and protrusions, adjusting the distance between the two first crawlers 507 allows the robot to travel smoothly on it and better perform demolition tasks. At the same time, when encountering narrow passages or obstacles, the distance between the two first crawlers 507 can be shortened so that the robot can pass smoothly. When the distance between the two first crawlers 507 needs to be increased, the motor 40 inside the chassis bracket 1 is used. The driving plate 406 is driven to rotate, and the driving plate 406 drives the first connecting rod 407 and the second connecting rod 408 at both ends to rotate. The setting of the driving groove 409 prevents the inner wall of the chassis bracket 1 from blocking the rotation of the driving plate 406. Since the ends of the first connecting rod 407 and the second connecting rod 408 are both rotatably connected to the driving plate 406, and the other ends are both rotatably connected to the rotating rod 404, the rotation of the driving plate 406 is not blocked. At this time, the first connecting rod 407 and the second connecting rod 408 respectively drive the two slides 402 to move in opposite directions. At the same time, since the two slides 402 slide between the two guide rails 401, To improve stability, the connecting rods 403 on the sides of the two slides 402 push the support frame 501 with the first crawler 507 installed in the two directions of both sides respectively. Since a connecting rod 403 is provided at both ends of a support frame 501, the two slides 402 at the other end of the chassis bracket 1 slide in the two directions of both sides along the two outer guide rails 401 at the same time, ensuring the stability of the support frame 501 during the outward extension process. At the same time, due to the sliding connection between the two reinforcing rods 509 installed on the side of the support frame 501 and the inner wall of the chassis bracket 1, the pressure of the fuselage 2 on the connecting rod 403 is reduced, avoiding The connecting rod 403 deforms under the action of gravity, providing strong stability. At this time, the motor 405 inside the chassis bracket 1 effectively drives the support frames 501 on both sides and the first crawler track 507 to extend outward, thereby ensuring the device's smooth travel on the ground, allowing the device to adapt to various complex working environments. At the same time, the pressure distribution on the ground is adjusted, making the device more stable when applying the demolition force, avoiding shaking or movement due to the reaction force, and ensuring the demolition effect and accuracy. At the same time, because the bottom of the chassis bracket 1 is installed with bolts, the bottom cover 410 can be easily removed to access internal parts for maintenance, which is highly practical.

[0034] Specifically, such as Figure 1-Figure 4 and Figure 6-Figure 8As shown, the walking structure 5 includes two support frames 501 and a hydraulic motor 502 installed at the end of the support frame 501, and the support frame 501 is fixedly connected between the two connecting rods 403 on the same side. The first driving wheel 503 is installed on the hydraulic motor 502, and the end of the support frame 501 away from the hydraulic motor 502 is fixedly connected to the mounting frame 504, and the mounting frame 504 is rotatably connected to the first rotating shaft 505, which is rotatably connected to the support frame 501. A guide wheel 506 is fixedly connected to the first rotating shaft 505, and a first crawler 507 is installed between the first driving wheel 503 and the guide wheel 506. A plurality of supporting rollers 508 are rotatably connected to the two support frames 501, and the supporting rollers 508 cooperate with the first crawler 507. Two reinforcing rods 509 are fixedly connected to one side of 01 close to the chassis bracket 1, and the reinforcing rods 509 are slidably connected to the inner wall of the chassis bracket 1. The two support frames 501 are symmetrically arranged, and the mounting frame 504 is a "U"-shaped structure; the two hydraulic motors 502 on the support frame 501 drive the fuselage 2 to move forward. First, the hydraulic motors 502 on the two support frames 501 drive the first drive wheel 503 to rotate, and the first drive wheel 503 cooperates with the guide wheel 506 on the mounting frame 504 to drive the first crawler 507 on both sides to rotate. At the same time, the supporting wheels 508 installed on the support frame 501 can provide an accurate running track for the first crawler 507, guiding the first crawler 507 to move forward or backward in a predetermined direction, preventing the crawler from running off, twisting and other problems during operation, and carrying the equipment itself and the load it carries.

[0035] Specifically, such as Figure 1-Figure 4 and Figure 6-Figure 8As shown, the rotating structure 6 includes a fixed frame 601 and a connecting plate 602 rotatably connected to the end of the fixed frame 601, two fixed frames 601 are fixedly connected to the side wall of the chassis bracket 1, and the connecting plate 602 is fixedly connected to the second rotating shaft 605. The upper surface of the chassis bracket 1 is fixedly connected to two connecting frames 603, and the connecting frame 603 is rotatably connected to the first hydraulic rod 604. The telescopic end of the first hydraulic rod 604 is rotatably connected to the second rotating shaft 605, and the climbing structure 7 is installed on the connecting plate 602; first, the first hydraulic rod 604 at the front end of the chassis bracket 1 starts to run, and the telescopic end of the first hydraulic rod 604 extends outward, and then the telescopic end of the first hydraulic rod 604 drives the connecting plate 602 to move around the fixed frame 601 The end portion rotates, at this time, the telescopic end of the first hydraulic rod 604 and the second rotating shaft 605 on the connecting plate 602 rotate, and at the same time, the end portion of the first hydraulic rod 604 and the connecting frame 603 rotate relative to each other, thereby ensuring that the connecting plate 602 can rotate smoothly. In the process of the telescopic end of the first hydraulic rod 604 extending outward, the angle between the connecting plate 602 and the fixing frame 601 gradually increases. When the connecting plate 602 and the fixing frame 601 approach the same straight line, the second crawler 704 installed on the connecting plate 602 will first contact the ground until the front end part of the fuselage 2 is lifted upward, until the front end part of the first crawler 507 is lifted upward and does not contact the ground, which is conducive to the subsequent adjustment of the spacing between the first crawlers 507 and has strong flexibility.

[0036] Specifically, such as Figure 1-Figure 4 and Figure 6-Figure 8 As shown, the climbing structure 7 includes a bracket 701 and a second driving wheel 702 rotatably connected to the bracket 701. The tops of the two connecting plates 602 are fixedly connected to the bracket 701. The side of the connecting plate 602 is provided with a third driving wheel 703, and the third driving wheel 703 is fixedly connected to the first rotating shaft 505. A second crawler 704 is installed between the second driving wheel 702 and the third driving wheel 703; by adjusting the angle between the connecting plate 602 and the fixed frame 601, the angle of the second crawler 704 can be adjusted. , and then when the equipment runs to a ditch or encounters an obstacle, by adjusting the inclination angle of the second crawler 704, the second crawler 704 is pressed against the ditch slope or obstacle, and the front end of the first crawler 507 is lifted a certain distance. At the same time, when the first crawler 507 is running, the first rotating shaft 505 on the guide wheel 506 drives the third driving wheel 703 to rotate, and the third driving wheel 703 cooperates with the second driving wheel 702 on the bracket 701 to drive the second crawler 704 to rotate, so that the equipment can climb up smoothly and pass through the ditch or obstacle, which is highly practical.

[0037] Specifically, such as Figure 2 and Figure 6As shown, the bulldozer structure 8 includes a mounting seat 801 and a connecting plate 802 rotatably connected to the bottom of the mounting seat 801, the side wall of the chassis bracket 1 is fixedly connected to the mounting seat 801, the end of the connecting plate 802 is fixedly connected to the push bucket 804, the top of the mounting seat 801 is rotatably connected to the second hydraulic rod 803, and the telescopic end of the second hydraulic rod 803 is rotatably connected to the connecting plate 802; when the second crawler 704 contacts the ground and lifts the front end of the chassis bracket 1 upward, the second crawler 704 located at the rear end of the chassis bracket 1 The two hydraulic rods 803 drive the connecting plate 802 to rotate downward around the bottom of the mounting seat 801 until the push bucket 804 at the end of the connecting plate 802 contacts the ground and lifts the rear end of the chassis bracket 1 upward. At this time, the two first crawlers 507 are effectively suspended, making it easy to adjust the distance between the two first crawlers 507, avoiding the first crawlers 507 from falling off due to the friction with the ground during the adjustment process. It is highly practical. At the same time, by lowering the push bucket 804, the soil accumulated on the ground can be effectively leveled, and the operation is simple.

[0038] When the present invention is in use, when the equipment travels to some complex terrain with bumps, potholes or slopes, the angle of the second crawler 704 can be adjusted by adjusting the angle between the connecting plate 602 and the fixed frame 601. Then, when the equipment runs to a ditch or encounters an obstacle, the first hydraulic rod 604 at the front end of the chassis bracket 1 starts to run, and the telescopic end of the first hydraulic rod 604 extends outward, and then the telescopic end of the first hydraulic rod 604 drives the connecting plate 602 to rotate around the end of the fixed frame 601. At this time, the telescopic end of the first hydraulic rod 604 is in contact with the connecting plate 602. The second rotating shaft 605 on the connecting plate 602 rotates, and at the same time, the end of the first hydraulic rod 604 and the connecting frame 603 rotate relative to each other, thereby ensuring that the connecting plate 602 can rotate smoothly. During the process of the telescopic end of the first hydraulic rod 604 extending outward, the angle between the connecting plate 602 and the fixing frame 601 gradually increases. When the connecting plate 602 and the fixing frame 601 tend to be in the same straight line, the second crawler 704 installed on the connecting plate 602 will first contact the ground until the front end of the fuselage 2 is lifted upward until the front end of the first crawler 507 is lifted. The first crawler 507 is partially lifted up and does not contact the ground. By adjusting the inclination angle of the second crawler 704, the second crawler 704 is pressed against the ditch slope or obstacle, and the front end of the first crawler 507 is lifted for a distance. At this time, the two hydraulic motors 502 on the support frame 501 drive the fuselage 2 to move forward. First, the hydraulic motors 502 on the two support frames 501 drive the first drive wheel 503 to rotate. The first drive wheel 503 cooperates with the guide wheel 506 on the mounting frame 504 to drive the first crawler 507 on both sides to rotate. At the same time, the supporting wheels 508 installed on the support frame 501 It can provide an accurate running track for the first crawler 507, guide the first crawler 507 to move forward or backward in a predetermined direction, prevent the crawler from deviating or twisting during operation, and bear the weight of the equipment itself and the load it carries. At the same time, when the first crawler 507 is running, the first rotating shaft 505 on the guide wheel 506 drives the third driving wheel 703 to rotate, and the third driving wheel 703 cooperates with the second driving wheel 702 on the bracket 701 to drive the second crawler 704 to rotate, so that the equipment can smoothly climb upward and pass through ditches or obstacles, which is highly practical.

[0039] When the second crawler 704 contacts the ground and lifts the front end of the chassis bracket 1 upward, the second hydraulic rod 803 located at the rear end of the chassis bracket 1 drives the connecting plate 802 to rotate downward around the bottom of the mounting seat 801 until the push bucket 804 at the end of the connecting plate 802 contacts the ground and lifts the rear end of the chassis bracket 1 upward. At this time, the two first crawlers 507 are effectively suspended, making it easy to adjust the distance between the two first crawlers 507, avoiding the first crawler 507 from falling off due to the friction with the ground during the adjustment of the distance, and having strong practicality. At the same time, by lowering the push bucket 804, the soil accumulated on the ground can be effectively leveled, and the operation is simple. By adjusting the two first crawlers 507 at the bottom of the equipment The spacing between the two first crawlers 507 can make the center of gravity distribution of the equipment more reasonable and reduce the risk of rollover. Since the ground may have various angles of inclination and protrusion, adjusting the spacing between the two first crawlers 507 can allow the robot to travel smoothly on it and better perform demolition tasks. At the same time, when encountering narrow passages or obstacles, the spacing between the two first crawlers 507 can be narrowed so that the robot can pass smoothly. When it is necessary to increase the spacing between the two first crawlers 507, the motor 405 inside the chassis bracket 1 drives the drive plate 406 to rotate, and then the drive plate 406 drives the first connecting rod 407 and the second connecting rod 408 at both ends to rotate respectively. The setting of the drive groove 409 avoids the inner wall of the chassis bracket 1 blocking the rotation of the drive plate 406. The ends of the two connecting rods 408 are rotatably connected to the driving plate 406, and the other ends are rotatably connected to the rotating rod 404, so as not to block the rotation of the driving plate 406. At this time, the first connecting rod 407 and the second connecting rod 408 respectively drive the two slides 402 to move in opposite directions. At the same time, since the two slides 402 slide between the two guide rails 401, the stability is improved. At this time, the connecting rods 403 on the sides of the two slides 402 respectively push the support frame 501 equipped with the first crawler 507 in the two sides. Since a connecting rod 403 is provided at both ends of a support frame 501, the two slides 402 at the other end of the chassis bracket 1 simultaneously slide in the two sides along the two outer guide rails 401, ensuring that the support frame 501 extends outward. The stability during the expansion process is enhanced. At the same time, due to the sliding connection between the two reinforcing rods 509 installed on the side of the support frame 501 and the inner wall of the chassis bracket 1, the pressure of the fuselage 2 on the connecting rod 403 is reduced, and the connecting rod 403 is avoided from being deformed under the action of gravity. The stability is strong. At this time, the motor 405 inside the chassis bracket 1 effectively drives the support frames 501 on both sides and the first crawler 507 to extend outward, thereby ensuring that the equipment travels smoothly on the ground, enabling the equipment to adapt to various complex working environments. At the same time, the pressure distribution on the ground is adjusted to make the equipment more stable when applying the demolition force, avoiding shaking or movement due to the reaction force, and ensuring the demolition effect and accuracy. At the same time, since the bottom of the chassis bracket 1 is installed with a bottom cover 410 by bolts,Therefore, it is convenient to repair the internal parts by removing the bottom cover 410, which is highly practical.

[0040] During the demolition of a building, the two first crawlers 507 at the bottom of the chassis bracket 1 drive the fuselage forward and backward. At the same time, a breaker hammer is installed on the fuselage 2 through the mechanical arm 3, which facilitates the rapid demolition of the building.
